Waste Caps – S51 Threads

To comply with waste handling regulations and prevent evaporation of volatile compounds, S51 waste caps fit all bottles or canisters with S51 thread. They have three ports with ¼-28 thread for 1/8" or 1/16" tubing and a fourth port with your choice of threads.

S51 waste caps seal the container with an O-ring behind a PTFE lip, so the O-ring is therefore not a wetted part. Unused ports should be closed with plugs.

A bottom-sealing barbed adapter to connect 4, 6, or 8 mm ID tubing can be ordered separately.

A VICI Jour waste cap package Includes:

• 1 cap, S51 thread
• 1 O-ring
• 1 set: 1/16" nut/ferrule/color-sleeve adapter
• 2 sets: 1/8" nut/ferrule/color-sleeve adapter

Caps with 1/2-20 thread also include:

• 1 1/2-20 plug
• 1 1/2-20 nut for 1/4" tubing
• 1 1/2-20 collapsible ferrule for 1/4" tubing

NOTE: One port must be reserved for the exhaust filter or the Safety Air Inlet Valves with Filters.
